EVBUM2623/D RSL10 Solar Cell Multi-Sensor Platform User s Guide Introduction www.onsemi.com The RSL10 Solar Cell Multi Sensor Platform (RSL10SOLARSENSGEVK) is a comprehensive development EVAL BOARD USERS MANUAL platform for batteryfree IoT applications for smart building, smart home, and Industry 4.0 verticals. Based on the industrys lowest power Bluetooth Low Energy radio (RSL10), the board features sensors for environmental and motion sensing (BMA400 a smart 3 axis accelerometer, BME280 a smart environmental sensor, and the NCT203 widerange digital temperature sensor). The board also features a low weight, low profile 47 F storage capacitor of a programming and debug interface and a connected solar cell. Since the device harvests energy from a low current source, it is important to minimize leakage of the overall system during operation and standby. Along with other energy efficient devices, an ultralow quiescent current LDO (NCP170) on the board significantly minimize leakage. Figure 1.
